• configurable storage backends for public and private files
• serve private files with permission checks
• smart serving (X-Sendfile)

• no more request objects in the models
• better ui
• auth backend
• cleaner

• e.g django-polymorphic-models

• collections are like structured tags ( a file can be in multiple collections)
• are folders still needed?

• no more dates in path (random numbers?, md5?)
• allow enforcing certain (physical) paths for certain files (e.g avatars should always be like /media/avatars/username.jpg

• file and image widget for use outside of the admin (upload only)
